Right click on PC companion.exe and select 'run as administrator', then install.If still not installing then download the application to pc from sony product support and install it. If problem persists give details.
tried as admin n downloaded from sony support still same problem what more details to give?
Hi, suggest you check system requirement for PC Companion.
Recommended system requirements:
Internet broadband connection
Intel® Pentium® 4, 3.6 GHz or equivalent AMD processor
500 MB free hard disk space
2 GB RAM
1 available USB 2.0 port and USB cable
Microsoft® Windows XP™ SP2 (32 bit), Vista (32/64 bit) or Windows 7 (32/64 bit)
Did you disable Anti-virus and Firewall during the installation?
yes
all requirements are met still not working
Possibly conflict between your PC and PC Companion?! Are you able to try on another PC/Laptop?
yes it works on other pc but before it would it work on mine also
I see, therefore confirmed that it is a PC issue.
Just to be sure, is your PC running on Windows 7?
yeah
i formatted full c drive n put 7 again still same problem 
As stated 'A problem caused the program to stop working correctly', guess you have to sort out that problem in Windows 7.
Are you able to restore your PC to factory settings? Definitely better than formatting it yourself, probably missing some steps/drivers during the process.
