UltraScan III Troubleshooting Tips:

Known Problems:

Cannot complete Registration (due to Network Failure During Registration)
UltraScan-III requires unhindered access to the ultrascan.uthscsa.edu port 80 http connection in order to complete the registration process. If the network is somehow blocked or unavailable during the registration process, there could be a mismatch between the information available on the license server (remote) and the information stored locally on your own computer. In this case, the easiest fix is to delete the local information and try again from another network connection that is not blocked by firewalls or lack of privilege. This situation most often occurs in corporate environments where firewall restrictions are extreme. In such a case, taking your laptop to an open network (say, at home) will often permit the registration to proceed unimpeded. The process required to reset the registration on your local system varies according to operating system:
- Linux:
  open a shell window and remove the UltraScan3 entry in your $HOME/.config directory:
```
rm -r $HOME/.config/UltraScan3
```
  and then re-register on a validated network
- Macintosh:
  You will likely find your settings in your home /Library/Preferences folder. Open a Finder window to your local Library:
```
   /Users/ultrascan-user/Library/Preferences
```
  Navigate down until you find a entry like:
```
   com.ultrascan3.UltraScan.plist
```
  Double-click on the entry and that should open Property List Editor. Within its window, select the entry for
```
   license
```
  then click (above) on Delete Item and then re-register on a validated network.
- Windows:
  You will need to use the registry editor from Windows to remove the UltraScan-III entry. Open the regedit.exe application and find the UltraScan-III registration entry, delete it, and then re-register on a validated network.
