WampServer

After installing wamp, I can't get the indicator to go all white, just half yellow. These are the two errors I get:

The procedure entry point php_set_error_handling could not be located in the dynamic link library php5ts.dll.

This application has failed to start because php_pdo.dll was not found. Re-installing the application may fix this problem.

When I look in services, mysql is started, and apache says "manual".. I think the only issue is with php..? I already was using php before I installed wamp.. could that have anything to do with it?

Any help would be great!!!

Thanks!!!

Update and new question....

I removed all php files and references to php in IIS. I uninstalled wamp, rebooted and reinstalled wamp. Then I got this error:

Could not execute menu item(internal error) [Exception] Could not perform service action: The service has not been started.

I stopped IIS.. then got this error:

Could not execute menu item(internal error)
[EAccessViolation]Access violation at address 004F19B5 in module 'wampmanager.exe' Read of address 00A2E228

If I understand correctly, I need to uninstall IIS.. is there any way to have both IIS and Apache (Wamp) running on the same machine?

Sorry.. very new at this.

uninstalled IIS and wamp works.. indicator all white!

Still would like to run IIS on the same machine since I have other projects using ASP/vbscript. Wondering if anyone can give me some quick instructions on how to do this....
