I've got VSTO project for Outlook, developed in VS 2012.
When I install it under Windows XP, where Visual Studio 2010 or later version is installed, I've got no problems.
When I install it by clicking .vsto file under Windows XP where no Visual Studio is installed, VSTOInstaller.exe fails with 0x8007007F error.
When I install it from command line (in fact it's the same)
"c:\Program Files\Common Files\Microsoft Shared\VSTO\10.0\VSTOInstaller.exe" /install file://.../OutlookAddIn.vsto
I get
The procedure entry point GetFileVersionInfoExW could not be located in the dynamic link library VERSION.dll
Windows installer 4.5, VSTO 2010 runtime are installed on the problem machine.
How to fix it? Thanks.
Finally I suppose VSTO 2010 runtime downloaded from https://www.microsoft.com/en-us/download/details.aspx?id=48217 has a bug in VSTOInstaller.exe (version 10.0.60724.0).
Uninstalling it and reinsalling older version from distributive of VS 2015/2012/2010 (find file vstor40_x86.exe or vstor40_x64.exe) fixes the problem.
VSTOInstaller.exe from VS 2015 has version 10.0.50903.0 - it is OK.
