When I add a Splash Screen using Launch4j, I get a Startup Error (“An error occurred while starting the application”)

StackOverflow https://stackoverflow.com/questions/9281832

Question

I noticed that Launch4j's GUI seems to prefer a bmp file, so I used Gimp to convert my jpg file into that format, but I kept getting the error when trying to run the executable generated by Launch4j.

Was it helpful?

Solution

I was on the right track by converting my jpg file into a bmp file. The Launch4j GUI allows you to choose any file for the Splash file, but it requires a 24-bit bmp file.

Initially, when I converted my file with Gimp, I converted it into a 32-bit bmp file. This was the cause of my problem. I reconverted the image using Gimp's default value of 24-bits and now the executable that Launch4j creates will run without an error.

OTHER TIPS

Make sure the following options are selected when exporting the BMP in GIMP:
