chm files dont open

[pscraja]

My system is as below:

Windows XP Professional Service Pack 3, v.5857 (build 2600)
2.67 gigahertz Intel Pentium 4
1984 Megabytes Installed Memory
Board: Intel Corporation D101GGC AAD35788-305
Serial Number: BTGC6090302D
Bus Clock: 133 megahertz
BIOS: Award BIOS for Intel GC11010N.86A.0303.2005.1108.2057 11/08/2005
409.95 Gigabytes Usable Hard Drive Capacity
Board: Intel Corporation D101GGC AAD35788-305

I am unable to open any chm file. When I open the file I get a message
"cannot open the file: mk:@MSITStore: " file location in the hard drive ending filename.chm"
I would like to know which program is causing the error. If some one can guide me I will be able to reinstall.
I have attached the snap shot of the file to understand the problem

thanks
