I was using msn messenger the last day ... and then I shut down my pc ( I have win server 2003 sp1 v 1023) When I came back ... I performed some cleanup operations with system mechanic and then removed some temporary files .... now my msn messenger was gone .... when I start its offline installation again ... it says " Insallation program appears to be damaged or corrupted. Contact the vendor of this application." By the way I am using msn messenger 7 beta. I then downloaded it again ... and it didnt work too showing the same message. Then I tried msn messenger 6.2 .... it also shows the same message. All other exe files on my pc are running properly.
I have got sygate firewall ... EZ eTrust Antivirus ... xsoft antispyware and system mechanic 5c.
what is the problem ??
