Is RequestExecutionLevel XP SP2 safe?
 

Due to a bug namespace handling in the little XML parser that resides in Windows XP SP2 (in CRSS.EXE, specifically, see KB921337), some commonly-formatted manifests can cause SP2 to Blue Screen. :eek:

There's workarounds (documented in the KB), but will including RequestExecutionLevel in the script embed XML in the manifest that might run afoul of this MS bug?

Thanks!

That is a Visual Studio 2005 bug

It's a CSRSS bug. But if the installers' manifests don't invoke it by redeclaring namespaces like 3 times over, as those generated by VS2005 do (for no particularly good reason), then that's good enough for me.

Thanks!

The manifest is safe. It doesn't use the version which CSRSS hates.

This is mt.exe 5.2 bug. MS wrote ( http://support.microsoft.com/kb/921337 ): "When parsing the embedded manifest, its internal memory can be corrupted if it finds a single tag that has two schema properties." but I had the same problem with single schema property. After I installed service, my XP started rebooting even before "Welcome" screen :( . So it is highly recomended to replace VS VC/bin mt.exe 5.2 with 6.0 version presenting in SDK/v2.0/bin folder.
