Problems installaing Parallel tools

Hi,
Thanks for this great programme. I am having problems installing the parallel tools when I am on Windows . It keeps saying "An error (-5004: 0x80029c4a) has occurred while running the setup"
Thanks,
Profetes

 

Different problem now

Now, I discovered when booting parallel with a dvd in the drive it doesnt recognise the dvd)cd drive; so there could be the original problem I had when installing the tools. Now I've tried with a cd, the drive works in theory, but when I try to install the tools it doesn't do anything.
Thanks!

 

Update

Now, I keep having the error I had at the beginning, even with a proper cd in the drive.

 

Same issue here with b3, except my error is -5009. The results are the same, though - I can't install the tools after repeated attempts and VM reboots.
