I recently had to set up a Brother DCP-L2540DW. For whatever reason, on one Windows 7 Pro machine, the installer would not complete. I got various error messages, all with InstallNetworkDriver in the description, some coded IS034 and IS052.
The printer worked out of the box with a USB cable. But I wanted to move it to a networked connection. This required the proprietary Brother software to get the network scanning to work.
The official Brother support page, The error message “IS052 InstallNetworkDriver” appears when installing the MFL-Pro Suite from the CD-ROM or the Full Driver & Software Package is downloaded from the “Download” section. didn’t help. Neither did random results from Google.
In the end, I ended up installing under a different administrative account!
The user account I had been using had full administrative permissions… but it just didn’t work. I suspect it’s my use of EFS encryption on multiple of my user folders, or maybe some weird conflict with the networking setup in my day to day user account, or something weird involving the virtual machines that I sometimes run, or maybe with the multitude of programs and devices that I end up installing or uninstalling via my account.
