[en] This topic describes how to upgrade both 64-bit and 32-bit drivers on your servers.
-
[en] Download the latest Loftware driver and run the .exe file to unzip and start your PrnInst application.
注意
[en] PrnInst does not upgrade your 32-bit drivers. After this step, 32-bit drivers remain on your servers unchanged.
-
[en] First, remove your 32-bit drivers. In Print Management, go to Drivers, right-click the driver you want to upgrade, and click Remove Driver Package...
[en] In Printer Properties > Sharing > Additional Drivers... select x86 to enable the 32-bit version of your driver and show the new driver location.
警告
[en] It is also possible to upgrade from Drivers and Printers > Printer properties > Drivers with the Add Printer Driver Wizard. But we don't recommend this procedure because it may cause problems with mismatched driver files and lead to print spooler crashes.
[en] After you upgrade your 64-bit and 32-bit drivers, verify the file creation dates. Your 32-bit and 64-bit versions should have the same timestamp.
[en] Compare the following files:
-
[en] "C:\Windows\System32\spool\drivers\W32X86\3\" for 32-bit.
-
[en] "C:\Windows\System32\spool\drivers\x64\3\" for 64-bit.

[en] Corresponding .dat files in both folders must be the same.
[en] Corresponding .dll files must have the same timestamp but should have different versions. You can check the versions by comparing the file sizes.
