The following occurs when using Lbplay2.exe: "ERROR: Please check WINNT\system32\drivers\windrvr.sys." This only occurs on PCs that have ISE6.2 installed. (It does not occur on PCs that have ISE6.1 or earlier installed) The solution to this is as follows: 1. Uncompress "wb_TE7720_software_20031104.zip". In the uncompressed folder there will be a file called "Release204.zip". Please uncompress this too. 2. After ensuring that there is no file with the same name, under an account with Administrator privileges, copy "windrvr.sys" to the following folder: EFor WindowsNT/2000: C:\WINNT\system32\drivers EFor WindowsXP: C:\WINDOWS\system32\drivers 3. Open a Command Prompt window, move to the uncompressed folder and execute: "wdreg install". Following the above steps will allow normal operation.
