Uninstalling Software
Note: If you perform a series of installations, uninstallations, and reinstallations, you run the
risk of corrupting the CDS_LIC_FILE environment variable on the file server or on the remote
client computer. If this variable is corrupted, you may be unable to run any products that are
still installed. For example, if you had a previous Cadence release installed, then installed and
uninstalled a new release, you may be unable to run any products from the previous Cadence
release. Once the CDS_LIC_FILE environment variable is corrupted, the only remedy is to
manually edit the environment variable and reset its value to reflect the license server
information, in the form of @. For example, the value of the
CDS_LIC_FILE environment variable for a single license server might be:
CDS_LIC_FILE = 5280@pc1
and for redundant license servers, it might be:
CDS_LIC_FILE = 5280@pc1;5280@pc2;5280@pc3
