Normally, if you have already installed and licensed ThroughFocus3, updating it only requires the downloading and replacement of a single, small file. The latest version is built on IDL (8.5.1). Please follow the instructions below.
Download tf3_sav_190403b.zip [3 MB] (the latest version)
- Download the t3_sav_yymmdd.zip file, linked above.
- Unzip the file. After unzipping, the file should be called tf3.sav with no date in the name.
- If you wish, rename the existing tf3.sav file, in your ThroughFocus3 folder, before you replace it. (I recommend giving it a date in the filename.)
- Replace the existing tf3.sav file, placing the downloaded version into the ThroughFocus3 folder.
- Launch ThroughFocus3.exe (Win) or ThroughFocus.app (Mac) as before. There should be no need to re-license the program if you follow these steps.
