This error typically indicates that the installation of GIFTS Alta that you are using has become corrupt. We recommend having a Computer Administrator or IT person rename the GIFTS.ini file (found in C:\Windows on the workstation).
Then they should reinstall Alta from the files they used to install it previously. This should resolve any issues in your installation.

If this issue persists after reinstalling Alta, then it could be a sign that your hard drive has become corrupted. Have an IT professional examine your computer for any hardware defects.
