# Floating License: disable Borrowing

## Licenses can be borrowed for offline use. The duration for which a license can be borrowed, can be specified in the license file. It is also possible to create an Options file for additional customization.

### Prerequisites

- KeyShot Licensing Server

### Procedure

Setting BORROW = 0 seems to be ignored by KeyShot and FlexLM and will default to 168 hours (1week).  
It is therefore advisable to set BORROW = 1 to the minimum borrow time of one hour.  
Since borrowing is enabled by default by the Flexera licence generator, if borrowing needs to be restricted or disabled, a workaround is required with the use of an Options file.

You can create a file named ***LUXION.opt*** and place it into the same folder that contains the license which is in the FlexLM License folder

- C:\\FlexLM\\
- C:\\ProgramData\\Luxion\\License
- MacintoshHD\\Applications\\LuxionLicenseServer\\Contents\\License

You can use the following options

- BORROW\_LOWWATER 
    - specified the amount of seats that cannot be borrowed  
      *BORROW\_LOWWATER keyshot2 **5***  
      this will exclude **5** KeyShot Pro licenses from being borrowed.
- MAX\_BORROW\_HOURS  
    - specifies the maximum amount of hours that a license can be borrowed. It needs to be lower than the than that specified in the license file for the respective feature  
      *MAX\_BORROW\_HOURS keyshot2 **1***  
      this will limit the borrow time for KeyShot Pro licenses to **1** hour.
