Symptoms

1. You are installing Acronis Backup & Recovery 10 Agent for Windows;
2. The installation stops with the following Windows message:

   Windows 32-bit: timntr_2k.sys is missing

   Windows 64-bit: timntr_64.sys is missing

3. Trying to manually add the drivers at this point from the %temp% folder results in the following error message:

   Error 1603 (Invalid parameter has been specified)

Cause

There are drivers left in the system from previous installations of Acronis True Image or Acronis Backup & Recovery 10. During the installation Acronis Backup & Recovery 10 erroneously tries to use the leftover outdated drivers instead of the ones shipped with the installation package.

Solution

• Run Windows search on the following hidden folder:

  /Windows/inf/

• Search there for oem*.inf files that are 0 KB in size. When found, look for their corresponding oem*.pnf files (files with exactly the same name, but with .pnf extension). For example:

  oem30.inf

  oem30.pnf

• Move both files to a different folder. Please note that there can be several pairs of files - you need to move them all;
• When all the files are moved, in the same /Windows/inf/ folder search for the oem*.inf files that do not have corresponding oem*.pnf files. Open the found files in any text editor (e.g. Notepad). One of the files should have Acronis instructions on TIMounter installation. Move this file to a different folder.
• Now, try installing Acronis Backup & Recovery Agent for Windows again. The installation should work.
