Hi, I would not attempt to do 2 full-blown installations of Inkscape on the same machine. You will almost certainly run into conflicts, either in the registry, or in the preferences file at: C:\Users\username\AppData\Roaming\inkscape. I would use a .7z version for the second (or third) version of Inkscape, which you can locate anywhere you like, preferably not underneath Program Files [x86].

just for curiosity, go to Control Panel->Programs and Features and check to see how many versions of Inkscape are reported there.

Hi Alvin, Since answering your last question, I've done a good deal of searching, to try and understand this issue a little better. (although my searching skills are probably weak) This is the top search result, no matter which combination of search terms I use. It only generally addresses my question about the 2 different program directories (at the top, and later goes into the op's specific question re IE). http://answers.microsoft.com/en-us/windows/forum/windows_7-files/programs... This is the best general explanation I could find, although I don't understand all of the discussion, which gets a little technical in some places. http://answers.microsoft.com/en-us/windows/forum/windows_vista-windows_pr... But the bottom line is that over and over again, I read the Program Files is meant for 64-bit programs and Program Files (x86) is meant for 32-bit programs. I read that generally the distinction is made because Program Files is better equipped to handle programs which use a lot of RAM, and having the 2 separate directories generally helps Windows to work more efficiently. Maybe the distinction is more and more moot, as the 64-bit type of computers are more common these days? But that's only me trying to make sense of why Inkscape wants to install its 64-bit version in the directory that's meant for 32-bit programs. My experience follows what I thought was true, that multiple versions of Inkscape can be installed without any problems. But I'm in no position to be able defend whether it really is true or not. Maybe I've just been lucky? (Although it should probably be cleared up, so that I don't continue to provide incorrect info to other users.) But I still remain curious about the 64-bit version of Inkscape wanting to install itself in the 32-bit directory (x86). I know from experience that RAM is often the limiting factor, when Inkscape drawings become larger and more complex (as opposed to processor or graphics card). I don't need a very technical explanation. But I'd really appreciate a simple answer :-) Thank you very much! -------------------------------------------------- From: "alvinpenner" <penner@...2467...> Sent: Monday, November 28, 2016 5:35 PM To: <inkscape-user(a)lists.sourceforge.net&gt; Subject: Re: [Inkscape-user] installing on Windows, 32-bit vs 64-bit

conflict between versions, therefore I would never install two versions on the same machine. I wouldn't install the exact same program on the same computer twice. It doesn't make sense, for one thing. But I thought that being different versions, they were not the exact same program. Plus, I've had this notion that it was ok to have different versions installed, as long as they are not in the same folder. I've been looking for where I might have read this "advice". But both the website and the wiki have been edited extensively over the last couple of years or so. It might have even been on the old website where I read it. I do remember reading, relatively recently, about a bug with an MSI version of Inkscape, which didn't check for previous versions, and tried to install into the same directory as the existing installation. I didn't read into the details, because much of it was too technical. But I thought it meant that Inkscape should check for existing versions, and put the new one somewhere else. But maybe I misunderstood that? Maybe the problem was that it should check for exising versions, and refuse to install if it found one?? Anyway, see my reply to Raymond Wan, for my plans re your suggestions.

My response was based on the fact that I am cautious by nature. Being cautious, I would like to avoid all possibility of confusion or conflict between versions, therefore I would never install two versions on the same machine. The fact that only one version of Inkscape showed up in the Control Panel->Programs and Features, even after multiple installations, would already be enough to cause me some concern. However, here is a possible explanation of your problem (just speculating). Assume that your first installation of Inkscape was a 32 bit version, and that it went into the (x86) folder. This fact will certainly be recorded in the registry somewhere, and it is possible that Windows may try to force _all_ subsequent versions to go into this same directory, regardless of their origin. Again, just speculating. One way to test this hypothesis would be to uninstall all Inkscape versions from your computer until the Control Panel entry for Inkscape is empty, and then try to do a 64-bit install to see if it installs normally into the right folder. Alternatively, what you could do is just take the easy way out, and use the 7z distribution, which is guaranteed to work with no hassles. good luck, Alvin -- View this message in context: http://inkscape.13.x6.nabble.com/installing-on-Windows-32-bit-vs-64-bit-t...

Hi Brynn, I haven't been following this discussion, but I hope you don't mind if I jump in... I agree with Alvin's suggestion and also his idea to uninstall all versions and then re-install the 64 bit version. (I would further suggest that you do a reboot prior to installing the 64 bit version, just in case.) However, you raised some interesting points which I'll try to answer, even though I'm not much of an expert with Windows...

So, by this, I mean if you download the 32-bit version and it "somehow" installs itself in the 64-bit Program Files directory, it doesn't "make it" into a 64-bit version. It is actually being installed in the wrong place. Placing them in two separate directories makes it easier to distinguish between two different versions of the same program. This is because a 64-bit Windows can run both 32-bit and 64-bit programs. But yes, 32-bit programs (running under 64-bit Windows) have access to less memory.

I think a program being installed correctly doesn't necessarily mean it is a good thing. You may have mixed up versions of programs that will cause headaches for you further down the road. Installation is a fancy term for copying a file. And often, when you copy a file, you don't check if there is a file already there and also, if that file is important to someone else. Installation programs are also like this. Suppose version 1 copies a file called abc.bin to a directory. Version 2 copies its abc.bin on top of version 1's. Now, you uninstall version 1. abc.bin gets deleted. When you try to uninstall version 2, it might flag an error because it says abc.bin is missing... This is one scenario that I can imagine when you uninstall all your versions of Inkscape, but at this stage, it's a bit unavoidable. I think uninstalling all versions of Inkscape is the way to go, but I wouldn't do it before a deadline. :-) Make sure you are in a patient mood before attempting.

Ok, so for uninstalling 32-bit, exe, 0.92, then restarting computer, then attempting to install 0.92pre3 of 64-bit Inkscape -- Inkscape does correctly want to install it in Program Files. So as long as there are no pre-existing versions installed, Inkscape does install to the correct directory. But for multiple versions, it does not necessarily. And the question about the safety of having multiple versions installed is still unanswered. For testing whether I am able to successfully uninstall my few different versions (on the other computer), will have to wait a little while. Tomorrow morning maybe. I'll post as soon as I've had a chance to try it. Thanks again :-) -----Original Message----- From: brynn Sent: Friday, December 02, 2016 10:24 PM To: Inkscape User Community Subject: Re: [Inkscape-user] installing on Windows, 32-bit vs 64-bit Thanks for your comments, Ray. Much appreciated. Since there hasn't been much response to this, which to me seems like a potentially serious problem/bug, I'm wondering if those who package Inkscape for Windows already are aware of this, but don't have time to explain it. 64-bit program only. I had to use the 32-bit version of 0.91, because of a bug in the 64-bit version which was bothersome. I felt it was fortunate that I had a choice. But I also understood that Inkscape wouldn't be using all my cores and memory threads (or whateve they are called). (I think it's been fixed for 0.92, so I'll be glad to switch back to 64-bit. your list of installed programs. The fact that it isn't is of course not your fault. But ignoring it may not be a good idea... Are you saying that what I thought was true, that multiple versions can be installed, as long as they are in different directories? Or are you saying the *if* multiple versions are allowed, they should both (or all) be shown in Programs and Features? Next steps for me depend on whether we are trying to find a solution to my problem (if I have one, I'm not sure), or whether we are trying to find a solution to a problem with Inkscape's installation. For me, my previously installed 3 or 4 or maybe even 5 versions (if you count 7z, I'm sure I have at least 1 or 2 of those) are on an old computer, which is on its last legs. I'm just about finished configuring my new computer (which is where I discovered this potential problem). The old computer has already died twice, and miraculously come back to life. So I've been avoiding major changes, such as installing and uninstalling anything. I've even been avoiding Windows Updates. Now that I have the new computer ready to take over, I'll probably see to the updates. If it can handle the updates, maybe I'll try to uninstall all the Inkscape versions I have. If it doesn't handle installing/uninstalling, I will only have this new computer to work with. I have only installed Inkscape 0.91, 32-bit on the new computer. So it will be easy to uninstall it, and try the 64-bit version. I'm on the new computer at the moment, so I'll go ahead and do that. But for uninstalling all the versions on the old computer, maybe later tonight. When I do all this uninstalling and installing, I will be transferring my same preferences.xml file from the old into the new. The prefs file has no bearing on this issue, right? And what about Inkscape versions? Should I experiment with 0.91 stable, or 0.92pre3? Or that doesn't matter either? But even if the 64-bit version installs correctly, I still would like someone to address the issue of having multiple versions installed. Do bug managers and testers use all 7z versions, when they do their testing? What if they have to test a problem with an EXE or MSI version?? This would be a really odd thing for my brain to have dreamed up, all on its own. I don't doubt that I read that from some authorative source. Seems like it might have been....I don't think more than 5 years ago. Thanks for everyone's attention and support. I'll post results of the first test shortly.
