We're having installation conflict between FileMaker Server 11 Web Publishing Engine and Lasso 8.6 on a Windows Server 2008 R2 running IIS 7.5. When FileMaker Web Publishing Engine is installed and running, Lasso stops working. When Lasso is installed and running, FileMaker Web Publishing Engine returns an error:
Server Error in Application "DEFAULT WEB SITE"
Internet Information Services 7.5
HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
Detailed Error Information
IIS Web Core
Lasso support cannot resolve the problem, and FileMaker support does not deal with third party software.
I know of machines with a similar configuration, running both FMS WPE and Lasso. The IIS version on these machines is 7.0.
Does anyone have a solution?
