We have a VB.NET applciation that is run from a mapped network drive. This works fine on all PCs expect those with Windows 7, on those we get the following:
“application generated an exception that cannot be handled” System.Security.SecurityException was unhandled
If the application folder is copied locally and run from there it works fine.
Anyone know a way aroudn this issue? I assume it is related to Windows 7 netowrk security but not sure how to work around it.
Well, normally you should get this error on all PCs, not only on your Win7 PCs. But I guess for your older Windows PCs someone has solved this issue some time ago. Read this article
