This tool lists all installed Windows 32-bit TSE versions in a drive or path.
The tool runs in Windows GUI TSE v4.41.35 upwards. It lists installations from TSE v2.8 upwards. For each found installation it lists all the version information it can find, which usually is a lot. It asks for the drive or path to search in.
For the average user it might be interesting to check if and where they have TSE installations on a particular drive, and what versions these are.
For me as a macro programmer it is necessary to know which external TSE versions in TSE's
read.me file match with which internal TSE versions.
And luckily I already keep lots of old TSE installations, both for compatibility testing and to determine since which version a new bug occurs.
The relevance of TSE's internal versions is this:
For macro programmers the macro language has an INTERNAL_VERSION compilation directive as of TSE v4.41.44 (18 Jan 2021). With this compilation directive a macro can use a new macro laguage feature in those TSE versions that support it, and provide a work-around or a graceful degradation in those TSE versions that do not support the feature.
An example of the tool's excessive output can be found by following the link.
