We create a test a Pak to a specific product version. But we want the latest version we release to work for whatever comes next from the manufacturer.
Let’s use Techsmith Snagit as an example. As of this writing, there are two paks for Snagit: 10 and 11.
The Pak for Snag it 10 has its Internal ILT set so it only delivers settings WHEN specifically version 10 of SnagIt is on the machine. The Internal ILT is set as follows:
When %ProgramFiles%\TechSmith\Snagit 10\SnagitEditor.exe FILE VERSION is between 10.0.0.0 and 184.108.40.206. OR the file %ProgramFiles(x86)%\TechSmith\Snagit 10\SnagitEditor.exe FILE VERSION is between 10.0.0.0 and 220.127.116.11.
But the Snag it 11 Pak has its Internal ILT set so it delivers when version 11 and up to 99 is on the machine. Its internal ILT is set as follows:
When %ProgramFiles%\TechSmith\Snagit 11\SnagitEditor.exe FILE VERSION is between 18.104.22.168 and 22.214.171.124 OR the file %ProgramFiles(x86)%\TechSmith\Snagit 11\SnagitEditor.exe FILE VERSION is between 126.96.36.199 and 188.8.131.52.
Let’s assume Techsmith Snagit 12 comes out, and users install it, or it otherwise appears on machines. It’s VERY LIKELY that the Pak we already created for SnagIt 11 will mostly work for the next version, version 12.
Then, when version 12 comes out, we test our Version 11 Pak with Version 12 of the application and we do one of two things:
- If there are NO updates at all to the Pak, we do nothing buy make a note in the readme file. We note that the Pak continues to work as expected.
- If a Pak DOES require updates:
a) We then CHANGE version 11’s Internal Filter to work SPECIFICALLY for Version 11.
b) We produce the Pak for version 12. And make its Internal Filter work for Version 12 to 99.
Now when SnagIt 13, 14, etc comes out, the version 12 Pak will most likely keep working with it.
This same idea extends, say to Firefox which gets updated quite often in VERSION number, but usually no new checkboxes or features appear in the Firefox Options.
In this way, newer versions of Firefox will “just work” when using our latest Firefox Pak.
