Why do you need PowerPoint on your server side? What would you do with it?

Hello Friend please do this....

First of all i want to know that you actually use that library in you code or project....

if yes then do this....

1) remove that configuration line from your web.config
2) then again assign the reference of that library to your project by right clicking on references and choosing add reference..

i think it will solve your problem...

or if you not use that library in side you project then just remove that configuration from your web.config..

you Interop.PowerPoint assembly not present in GAC (c:\windows\assembly).
get the file and drag it to c:\windows\assembly. (you can not copy the file to GAC)
