|Thanks for your answer, but I cannot find much out of the ordinary. I am not very well familiar with the manifest, but it looks to be generated by Studio2010? Anyway, it reads:
<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'>
<requestedExecutionLevel level='asInvoker' uiAccess='false' />
There is no RT_MANIFEST mentioned in the resource
Also, the MinimumRequiredVersion is left blank, so I don't expect any difficulties there!
In any case: the program itself runs and it does everything up untill the point that I start the dialog box. (and everything after that dialogbox crashes) There are a number of log statements before and after and I see everyone of them. Only everything that occurs from within the dialogbox doe not appear in XP.
