4. On the Product Information button, locate the product version.
• If the product version is B.219.0 (UNICODE), proceed with installation.

• For AutoCAD LT 2008 rename the acadlt.exe file to acadlt.bak.
• For all other products rename the acad.exe file to acad.bak.
9. Download the appropriate zip file and extract the acad.exe file or the acadlt.exe file to a temporary folder; for example, c:\Temp.
10. Locate acad.exe or acadlt.exe in the temporary folder and copy it to the product installation folder found in Step 7.

NOTE: To remove this hotfix, delete the new acad.exe file or acadlt.exe file that you copied to the product installation folder and restore the file you renamed in Step 8 to its original name.
