Windows7, Vault, and SQL Server 2008 Issues - Resolution

If you are getting the following error, then try these steps to correct the issue.

regsvr32 actxprxy.dll

If that does not work try:

for %1 in (%windir%\system32\*.dll) do regsvr32 /s %1

for %1 in (%windir%\system32\*.ocx) do regsvr32 /s %1

If that still does not work try this as a final step.

x86: regsvr32 "C:\Program Files\Internet Explorer\ieproxy.dll"

x64: regsvr32 "C:\Program Files (x86)\Internet Explorer\ieproxy.dll"

Interestingly enough I had to perform all of these steps to correct the issue.
