ENTSSO failure on Windows 2008 64-bit

In BizTalk

This post is about the ENTSSO failure after having installed Visual Studio 2010 in your BizTalk environment.

The problem

After having installed Visual Studio 2010 on my 64-bit Windows 2008 server Enterprise Single Signed on stopped working. The event log tells us to call “regasm SSOSQL.dll” – which is very nice. Only it doesn’t work on 64-bit operating systems.



You need to explicitly call the 64-bit regasm tool from this location: “C:WindowsMicrosoft.NETFramework64v2.0.50727regasm.exe”. The event log entry also doesn’t tell us where the SSOSQL.dll is located. Well, here it is: “C:Program FilesCommon FilesEnterprise Single Sign-OnSSOSQL.dll”.

The command to execute

With brackets and everything.

“C:WindowsMicrosoft.NETFramework64v2.0.50727regasm.exe” “C:Program FilesCommon FilesEnterprise Single Sign-OnSSOSQL.dll”

Reboot and you should be on your merry way!
