ESP for 7.4.2 fails on Windows 7

Embedded Devices NET+OS

I’ve installed and used ESP (1.4.1) on Win XP without trouble.

I installed it on a Win7 machine today, and ESP won’t startup – the following is the error from the log.

Any suggestions?

Win7 32bit I assume?
I’ve googled for your error: "no swt-win32-3139 in java.library.path
" and found bunch of useful links including this one.

I’m running Netos 7.4.2 myself on win7 x86_32 and have no problem besides having to install latest Segger drivers for Win7 from Segger’s web site

3

Just for giggles, I decided to do an Uninstall, then install it again.

For whatever reason it worked this time.

Technically I did do a Customize install, but just left all the usual defaults. Whether that helped or not, who knows.

– gw

I’ve seen the error above when you have AVG running, and it blocks the Java portion of the install

5

AVG – beats me if that was running. Fresh install of Win7. Not really a Windows user – only for web testing and now the Digi development.

However, I did ask support, and officially Win7 is not yet supported but soon will be. Sounds like people may be using it successfully though.

For what it’s worth, if anyone else is stuck using Digi ESP in 2024 and beyond:

Run the setup as administrator (or launch it from an elevated prompt). Not sure why, but this seems to ensure everything is installed correctly. Installing as a regular user seems to cause the “no swt-win32-3139 in java.library.path” error unless Digi ESP is launched as Administrator.

Also, when launching Digi ESP for the first time after installation, launch it as administrator. After this, launch it regularly, you do not want to compile stuff as admin, especially not with a corporate system that (rightfully so) logs use of privileged operations. All those logs will slow down compilation significantly.

For me this works ok-ish with Digi ESP 7.2 on Windows 11, but it took a lot of trial and error to figure out.
