Error when Installing CorelDraw X5

I have tried installing CorelDraw X5 on my computer several times, but the installation is failing.
Twice, I have downloaded the trial version of Coral Draw from the official website of Coral but I am still facing this problem. Every time the installation starts, I get the following error popping up on my screen which reads as,

CRC error: The file C:UsersA2AppDataLocalTempCorelDraw Graphics Suite X515.0.0.489CGS15Common.cab doesn’t match the file in the setup’s .cab file. The medium from which you are running the setup may be corrupted; contact your software vendor.
I would be really grateful to you people if you have any idea regarding why I get this error and it keeps popping up every time and give me a solution regarding how to fix it up.
I would be waiting for your replies regarding this problem.
With Best Regards
