When you say 'signed the CSP" I assume it's not signed by Microsoft but
test-signed (by you). In newer Windows versions that will not help, ie.
Windows will not load your CSP - unless a Kernel debugger is loaded on your
system. Note that it is not required to USE the kernel debugger - you can use
your app-level debugger - only that it is present on your system.
An alternative solution is to patch advapi32.dll to disable this checking.
Search for posts in this forum with keyword "advapi32" and you will find
posts for various versions of that dll to be patched for CSP testing.
