I don't think there is a way of attaching files to this forum so I cannot send you a .reg file.

But if you open notepad and paste the following into it, assuming you have 64 bit windows.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{69C76448-D4B8-4886-A848-61CD4EB4B2C7}]

 then save the file out as trados2007.reg - make sure to change the 'save as type' to all files (*.*) not text documents (*.txt) as the .reg extension is important.

The double click the saved .reg file and say ok to the security warnings, you should get three prompts.

Then try the install again.

If it doesnt work you may have 32 bit windows so delete Wow6432Node\ from the line in the reg file and try again.
