Last week when I was trying to install WAMP Server on my office computer to do some PHP coding, I found out that when I access localhost (http://127.0.0.1/) this error appears.

error ‘8002801c’

Error accessing the OLE registry.

/iisHelp/common/500-100.asp, line17

I searched around the net for possible solutions…

(1) On Internet Explorer it works fine but in Firefox the error appears.
(2) Windows is not installed correctly, and some files are corrupted.
(3) IIS and .NET Framework incompatibilities.

and some others. But the best solution I used was disable IIS completely, since I’m not using it anyway. But if you are using it (like for .asp) then don’t do this.

Remember that I’ve used this method for WAMP (Apache, MySQL, PHP) to work on my PC.

Solution after the gap.
