Installation of Office Pro 2007 - Error is not a valid Win 32 application

Question

I am using MS office Pro trial on widows 7 operating program and have just brought the full retail version.
When I insert the installation disc the program will not install, after about 5 minutes I get a message"
*D:\is not a valid Win 32 application.*
The retail version I brought is certified for windows vista, I loaded on my PC which is running XP and the disc worked as should.( I did not go through with the install on the PC, I just tested the disc)
I copied onto a external hard drive and tried to load it from there. No go!
I even used my product key code on the trial program but it rejected it!
Any ideas out there would be most helpful

This may get round the problem if its related to "old" progs on your install disc. I used this method when installing Office 2007 with a packaging date of March 2007 in case it saved lots of product update downloads - worked perfectly but I still had 20+ updates downloaded after install.
If you have a reasonable broadband speed then [dowload the Office 2007 trial|http://us20.trymicrosoftoffice.com/default.aspx] . MS email and display a trial product key but when the download starts to run don't use this key but your own "full" version product key
Just re read your post - you are going from trial to full so what you do is follow MS instructions
Follow these steps to activate the trial:
Follow these steps to convert the trial:
You can convert from the trial software to a full-version either before or after your trial period ends.
Before the trial period ends:
You will start receiving expiration reminder messages indicating the date when the trial will expire. At this point, you can convert to the full product in two ways:
1. In any of the expiration reminder messages, click Convert, and then follow the steps in the conversion process, below.
2. At any time during the trial period (or even after the trial has expired), you can open any of the Microsoft Office System products, and in the Help menu: click "Activate your software".
After the trial period expires:
The software goes into reduced functionality mode. Some of the limitations of reduced functionality mode include the following:
- You can not create any new files.
- You can view existing files, but you can not modify them.
- You can print files, but you can not save them.
