Simple question about an hypothetical way to "be able or not" to install a Mixed (32 and 64 Bit) Microsoft Office System...

Hello again to all,

This time I have only one very simple question as simple than the tittle itself is enough to understand it...

Do someone knows an efficiant way for me to keep my actual installed Microsoft Office (64-Bits) Pro 2010 Suite to be able continuing working on some of my insanely huge "*.xlsb" documents containing many "Matricial-Formulas" over 700'000 rows and to be able to install at the same time on the same System a new fresh MS Office Pro 2013 (32-Bits) version allowing me to use the "xlPrecision" plugin that is only working on (32-Bits) versions ?

I guess it wont be possible to do it easily, so maybe there is another way to "Virtualize" only Microsoft Excel (Any Versions) allowing it to use all the computer performances ?

Thanks in advance for your answers!

See you soon .. ... .....

Best regards,

JN

Office setup is doing a lot in the OS, so I doubt you can do that easily. However, you can try if a copy of an 32 bit Office installation works. And of course you can use a VM, but that is a lot of effort.

Well, what deep influence is it having? The first thing I think of is setting file extension associations to the newer Office applications. But that doesn't hinder you to start the older Excel2010 64bit to open large files from it and start Excel2013 32bit to open sheets capable to integrate the xlPrecision plugin.

Bye, Olaf.
Having different Office releases (e.g. 2010 and 2013) is not the same as having different bitness. As you correctly elaborated, version specific entries can be used, and the most recent installation determines the defaults used.
But with different bitness it can make a difference where and whether "system" DLLs are installed. Version mismatches can cause strange (failing) behaviour.
JN, if you're using the applications "manually" (normal) and there is no application doing office automation, eg an Access database outputting Word documents, I don't think there is anything to fear from the parallel installation, I just don't know how easy it is to specify you don't want to upgrade but make a separate install. It's possible from the experience of the Access developer I know, I may ask him about special preparations for this, but I don't have much doubt about it, especially if you pick to install only Excel 2013.

Bye, Olaf.
