BugNET

As an XP user i was also getting the same error....

This error is usually caused when .Net is installed before IIS.

Try these steps at the command prompt to resolve this issue:


STEP 1 - Uninstall ASPNET from IIS

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -ua

Start uninstalling all versions of ASP.NET.
..............
Finished uninstalling all versions of ASP.NET.

STEP 2 - Remove ASPNET user from Machine

Navigate to Control Panel -> Administrative Tools -> Computer Management -> Local Users and Groups

STEP 3 - Install ASPNET again (this will also create the ASPNET user)

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -i

Start installing ASP.NET (2.0.50727).
................
Finished installing ASP.NET (2.0.50727).

STEP 4 - Grant ASPNET user access to the IIS metabase

Note: you would need to substitute gaurav001 with the name of the machine you are attempting to install Enterprise Architect onto.

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -ga gaurav001\ASPNET

Start granting catchlaptop004\ASPNET access to the IIS metabase and other direct
ories used by ASP.NET.
Finished granting catchlaptop004\ASPNET access to the IIS metabase and other dir
ectories used by ASP.NET.

STEP 5 - Restart IIS

Control Panel -> Administrative Tools -> Internet Information Services -> Right click on Computer -> All Tasks -> Restart IIS...

At last you have to allow general sharing on the BugNet application folder.

This should resolve your problem.

All The Best.
