Here's my situation:
I'd like to run Paint.NET on a Windows computer where I don't have admin privileges (e.g. college computer).
I've tried following the instructions [ https://forums.getpaint.net/topic/113484-paintdotnet-in-a-zip-file-no-installation/ ] to install on another computer and copy across, but I can't do that with my Mac :)
There is a solution! (You won't get file associations or a Start Menu icon, but at least you can run it.)
First, open cmd (Command Prompt) and run the following:
cd %USERPROFILE%\Downloads
tar -xf paint.net.4.2.16.install.zip
SET __COMPAT_LAYER=RunAsInvoker
paint.net.4.2.16.install.exe
(Note that "tar" is only available from Windows 10 April 2018 Update onwards; if you don't have it, just unzip the file manually.)
When you enter the last command, the installer starts running; and if you click "Show Details", you can see it extracting extracting its files to a temp folder.
After all the files are extracted, the installer comes up with a warning:
Administrator privilege is required to install paint.net
[OK]
Don't click OK on that popup just yet!
Open up a Windows Explorer window, and browse to %TEMP% (usually C:\Users\<your_name>\AppData\Local\Temp)
Find the folder called PdnSetup and copy it to C:\Users\<your_name>\Downloads\PdnSetup
Now go back to the warning popup and click OK. The installer will now delete %TEMP%\PdnSetup.
Open a new command window, and type in:
cd C:\Users\<your_name>\Downloads\PdnSetup
msiexec /qb /a PaintDotNet_x64.msi TARGETDIR=C:\Users\<your_name>\Downloads\PaintDotNet
The installer will now create a portable version of Paint.NET in the target directory specified.
You can now run PaintDotNet.exe in C:\Users\<your_name>\Downloads\PaintDotNet
If you plan to use it often, I recommend using "Pin to taskbar" to get quick access.
Don't forget to delete the temporary folder PdnSetup, as well as the original paint.net.nnnn.install.zip and paint.net.nnnn.install.exe files.
Enjoy!
