FLEXlm Versions

I.1 Version Compatibility and Components

In general, always use the latest lmgrd and lmutil/LMTOOLS, which are available from www.macrovision.com, and you’ll automatically enjoy many of the enhancements available in the most recent versions of FLEXlm. However, some enhancements require a vendor daemon built with a newer version of FLEXlm, and yet others require a FLEXlm-licensed application built with a newer version of FLEXlm. Contact your software vendor for the most current version of their vendor daemon.

The rules about FLEXlm version compatibility can be summarized as:

Version of lmutil/LMTOOLS must be >=

Version of lmgrd, which must be >=

Version of vendor daemon, which must be >=

Version of FLEXlm-licensed application, which must be >=

Version of license file format

Except for the license file, you can use lmver to discover the version of all these components. For the vendor daemon, lmgrd, and lmutil, you can also use the -v argument to print the version.

I.2 How to Tell the License File Version

The following rules apply to individual FEATURE, INCREMENT or UPGRADE lines. It’s possible to have a mix of versions in a single file. Only the features that a particular application checks out determine the version of the license for that feature.

Version 2	Blank quotes or a quoted string at the end of the FEATURE line.
>= Version 3	INCREMENT or UPGRADE line.
>= Version 4	OVERDRAFT, DUP_GROUP, INTERNET, or PACKAGE appear.
>= Version 5	SUPERSEDE, ISSUED, USER_BASED, HOST_BASED, or SN appear.
>= Version 6	START appears.
>= Version 7.1	SIGN= keyword appears.
>= Version 8	BORROW, FLOAT_OK, and TS_OK appear.
