Hi faolie,
what operating system are you running?
the operating system required are:
Windows 2000 services pack 4
Windows xp services pack 2 and others
although I don’t think its a good idea to run on such operating systems such as windows server 2003 services pack 1 because high levels of memory and space is needed
Is recommended that your processor runs on 1 GHz or higher, though it can still work at a lower processing speed as time will be consumed.
Your RAM sounds good (recommended 256 MB)
And the full installation is 1.3 GB, you computer will be using the required I/O when running vwd through the RAM at a minimum of 192 RAM. I hope this helps?
