Updated Build will not install

I have tried to reinstall TI 7 build 638 several times and each time I get error message that tells me install cannot take place because of an error. The error is not defined. When I first tried to install build 638, my then current installation was removed by the new build. Now, I do not have TI installed and I need to backup my entire system. I NOW wish I had not tried to install build 638.
I have been trying to do this since 10-17-04. I emailed Acronis Support that night and just heard from them today. They sent two files for me to put in the
C:\Windows\System32\Drivers but it still won't install. Oh, the two files were: timntr.sys and snapman.sys. I have sent Support another email.
Any one here having this problem? All help will be appreciated.

 

Hello buf,

These files are the special versions of our low level drivers. Please continue working with support@acronis.com.

Thank you.
