I have been facing problem regarding installing softwares for about 2 years.
For example when i try to install adobe softwares i receive this error.
The cabinet file 'Data1.cab' required for this installation is corrupt
Also having problems installing microsoft softwares.
Mainly i face problem when i try to install large softwares. Small ones are installed without any problem.
Sometimes i download software. It is installed without any problem. but when i try to install next time it is corrupted.
From cd i face less problems as compared to computer hard disk.
I have tried almost all anti virus softwares. Nohting found. Once i deleted all partitions. it also did not solve the problem
I don't know whether is virus or hard disk is corrupted or problem is in the ram.
My pc has no other problem. It is working fine.
