Unable to install any version of Parallel Studio

I am trying to install Parallel Studio XE Cluster Edition in my workstation laptop. However, I am unable to do it because a "Package checksum verification failed" error always pops up irrespective of the version or the mode (online or offline) of installation. I am not sure what to do; I have tried it more than 10 times.

I was just using it two days back but had to uninstall it due to some problems in Visual Studio. Now I am unable to reinstall it. 

Even during un-installation, I could not do it from the control panel for the same reason ("Package checksum verificaion failed"). The uninstallation just would not proceed. At the end, I had to simply delete the entire installation folder and remove all the registry entries. I removed all other temporary files and leftovers etc.. 

Now the same problem is happening while reinstallation.

Is there anything that I can do?
