Client won't launch from gateway ver7.9.3

When attempting to launch a project from the gateway page I get the following error:

"Windows cannot access the specific device, path or file. You may not have the appropriate permissions to access these files."

This is on a computer in which Ignition was working before. A hardware issue (power supply) was repaired, and now they are getting this error. The customer changed some network settings, but then changed them back. Nothing else has changed that I am aware of.

The customer says that they are selecting 'run as administrator.'

Most likely there was an upgrade to java, and it deleted the old version you need to run old Ignition (java8 with webstart--gone from newer java due to serious vulnerabilities).

You should consider upgrading Ignition at least to the last v7.9.x, and then using the local client launcher instead of webstart.
