I have printed out the Excel spreadsheet of all of my VSt plugs. Since I have no old projects, how about I delete the 32 bit ones and be done with it? Just checking before hand......Am I correct that ALL 64 bit plugins tell you that they are 64?  Focusrite put both in the same x86 folder.

I've wondered about that myself. I've installed some plug-ins that were supposedly 64-bit but ended up in the x86 folder. Perhaps some of the Big Brains around here can enlighten us...

Rather than delete them (which you might regret later) just exclude them in Plugin Manager

I agree with Jonesey, those files really take up very little space and do not "auto start," so not an issue other than being "visible."

You can also exclude the x86 path from the VST scan. Some of those plugs are actually useful in other programs that only have 32-bit versions (like old copies of Adobe Audition).

As I understand it (though I may be wrong) the reason for the different 64 and 32 bit program files directories is to ensure 32 bit stuff that has no knowledge 64 bit environments even exist doesn't try to access the 64 bit version of a shared library file (dll) and fall over.

If an installer puts a 64 bit anything in the x86 directory then it's a badly written installer.

I guess a stand alone 64 bit VST dll might work OK if in x86, but if it tried to access a 64 bit shared library Windows might get a bit upset.

See, that's what I like about this place.
 
Plugin Manager.
 
I watched the X2 video as well, but my crazy neurons got it all fouled up..

I still got the old 32 bit plugs installed, but for anything acquired in the last 2 years I only install 64 bit (because I don't buy unless 64 bit) ...
 
Still, I did not delete any of the 32 plugs, but I use custom plugin layouts where basically only 64 bit plugs are listed and the very few 32 bit exceptions I have explicitly labelled with "pluging name (32 bit!!!)" ... doing so I've never had a 32 bit plug in the project when I owned the 64 bit version ...

I can't answer the question directly but I know that Sonar 64 bit seems to run much better since I eliminated the use of 32 bit plugs. I picked up a free copy of audition 3 and can't use the 64 bit plugs with it, but hopefully we'll have a wave editor built in one day and it won't matter. 32 bit will soon fade in the rear view mirror.

FYI, 32 bit and 64 bit plugin names are color coded in plug-in manager.
That should help you see at a glance which ones are 32 bit.

I don't see any color coding. They all look the same to me... blue
