On some Windows computers with very high resolution screens, for example the displays on Microsoft Surface 4 computers, CodonCode Aligner windows and fonts are very small. This post describes a solution to this problem. Please note that this problem only affects high dpi displays on Windows; it does not affect most regular monitors (with typical resolutions up to 1920 x 1080 pixels), or most laptops with "HD" displays, or Mac computers.
Basic Instructions
To solve the problem, click on this link to download a ZIP archive that contains a small program (.bat file) that first changes system settings to work around the problem, and then starts CodonCode Aligner. Depending on your browser, you may need to right-click on the links and choose "Save As" to download the file, or choose the "Save" option in a dialog.
After downloading the ZIP file, locate the downloaded file, and extract (unpack) its contents to your desktop or another location of your choice. To start CodonCode Aligner, double-click on the extracted "Run CodonCode Aligner.bat" file. The first time you do this, you may see a security alert; on Windows 10, the message states "Windows protected your PC". To start the program anyway, click on "More info", and then "Run anyway".
Double-clicking on Aligner project files
If you typically start CodonCode Aligner by double-clicking on Aligner project files, there one more step you have to do:
- Open an Explorer window and find a project file
- Right-click on the project file
- From the popup menu, select "Open with", then "Choose another app"
- Make sure the checkbox "Always use this app to open .ccap files" is selected
- Click on "More apps"
- Scroll down the list of programs, and select "Look for another app on this PC"
- Navigate to where you installed the "Run CodonCode Aligner.bat" file, and select it
- Click "Open"
Non-standard install locations
The .bat file assumes that CodonCode Aligner is installed in the default directory (C:\Program Files\CodonCode Aligner). If you installed CodonCode Aligner in a non-standard location, for example on a different drive, you will need to change the "Run CodonCode Aligner.bat" file. Open the file with an editor like NotePad, change the line that contains "C:\Program Files\CodonCode Aligner\CodonCode Aligner.exe" to point to where you installed CodonCode Aligner, and save the file.
