During a migration from a Single Gateway to a Cluster, we replaced the old gateway object with the new cluster object using the standard Replace feature in SmartConsole.
After establishing SIC successfully with the new cluster, the first Access Control Policy installation failed with the following error:
Policy installation failed on gateway. If the problem persists contact Check Point support. (Error code: 0-2-2000262)

Initial Investigation
The first step was to review SK154435:
Policy installation failed on gateway. If the problem persists contact Check Point support (Error code: X-XXXXXXX)
However, this SK does not contain any information regarding Error Code 0-2-2000262.
Next, we reviewed the policy installation report located at:
$FWDIR/state/__tmp/FW1/install_policy_report.txt
The following error was found:
loadUsermodeMt failed for load_prepare ERROR
loadmode load prepare failed ERROR
InstallPolicyMgr ERROR

At this point, several things made the troubleshooting confusing:
- SmartConsole Verify Policy completed successfully.
- No Validation Errors were reported.
- The policy appeared completely valid.

Root Cause
After opening a TAC case, the support engineer mentioned having seen this behavior before.
The issue can occur when a Gateway or Cluster object exists in the VPN column of an Access Control rule.
This configuration is not supported.
After reviewing the policy, we discovered that the large Replace operation had unexpectedly inserted the new Cluster object into the VPN column of several rules alongside the VPN Community.
This appears to be an unexpected behavior (possibly a SmartConsole Replace bug), because Gateway or Cluster objects should not be present in the VPN column.
Solution
The fix was straightforward:
- Review the affected Access Control rules.
- Remove the Gateway/Cluster object from the VPN column.
- Leave only the appropriate VPN Community object or any.
After removing the Gateway objects from the VPN column, the policy installation completed successfully.
Conclusion
If you encounter Policy Installation Error 0-2-2000262, especially after replacing gateway objects during a migration, it is worth checking the VPN column of your Access Control rules.
