This is a PSA, no answer required.

We recently ran into two situations where a product would not install, throwing a dialog box with nothing more than the message: 1:1712.

This took place at the step labeled, "Committing System Changes".  On OK, the installation is rolled back.  This turns out to be a Windows issue, where a prior installation of the same product failed.  It is not really a Laserfiche problem, although it affects what you are trying to do with Laserfiche.

There is no one remedy for this issue. Typically, you'd look in Add/Remove programs to see if any entry there is listed.  If so, uninstall and try again.  Also, a key in the registry might have to be removed.

One conflict involved the Windows Client. Here we found an entry in Add/Remove Programs for the Black Ice Driver.  Once that was uninstalled, the Win Client installed without issue.

A second conflict involved Workflow.  Running it from the menu (install everything) did not work.  But we were able to install one at a time the Designer, then the Server, then the Subscriber.

For diagnostics, you can run the installation from a command line with logging. Use this syntax:

"Path to installation program" -log "Path to log File"

As in: 

D:\10.2.0.872\en\WindowsClient\Setup.exe" -log "C:\temp\Client Installation Log.txt"
