While I'm happy to be correcd, I don't believe that you can do that, & I'm pretty sure that the option that been deliberately hidden for that reason.

The target framework of the server is already .NET Framework 4.0. The target framework of the client is Silverlight 5.

Any reason why my LS 2012 App won't install on Windows XP SP3 but installs and works great on Windows 7 64bit?

The Publish settings are as follows:

App Type:  Desktop

App Server Config:  Local

Prereqs: Microsoft .NET Framework 4 (x86 and x64)

Really basic app

only Two Extensions (LS Cosmo Shell and Theme / MS LS Extensions 1.0

Thoughts or Suggestions?

Sorry but why use Windows xp... it is dead start moving away from it...

On another note, it looks like you are compiled for x64 and trying to run on a x86 (32bit) machine. This is nothing to do with the targeted framework.

Hi,

I have exactly the same problem. I've developed my LS app on an x64 machine and want to install it on a mixture of W7 and XP machines. In my situation, we would have to upgrade the physical PCs to upgrade to W7 and we simply don't have the money. 

I'm desperate to get this working. What do I need to do?

I've tried using:

editbin setup.exe /SUBSYSTEM:WINDOWS,5.01 /OSVERSION:5.1

which changed the error to:

the procedure entry point InitializeCriticalSectionEX could not be located in the dynamic link library Kernal32.dll

Help!
