"Access denied" error during license checkout
An Some LM-X client library functionality that involves License Server features that you and/or your end user may optionally enable involve storing client data. For example, for example borrowing or checking out a floating licenses license with enabled automatic server discovery requires require OS-level synchronization between different processes.
If initiating one of the above actions fails under Windows, LM-X may return an the error code LMX_SYSTEM_INTERPROCESS indicating a resource locking error. Furthermore, if you want to borrow a license by setting the environment variable LMX_BORROW, you may see the following error:
Unable to checkout: LM-X Error: (Internal: 23 Context: 23) Access is denied.`
To resolve this issue, remove any temporary or data directory, which is named after `boost`, `boost _interprocess` or `lmx.interprocess`. In most cases, removing only `CC:\ProgramData\boost_interprocess` should interprocess should solve this problem.
