I have tried to create a a SFX installer, but nothing.
I select msi or folder I want include in my sfx.
I click on create and when I click with double click on created .exe file the same error appear: "Extraction Failed File is corrupt".
not sure whats the problem with the msi when click to create it uses lots of resources chokes the memory maybe you can find some other plugin or check again what process's are running with msi sfx script or something in the script ,or maybe its this 7za not sure what you have running inside 7za.exe for msi upx or whatever but this plug in is badly build
I have a similar problem if I have other file in same folder that msi file. Because my system make a sfx with all file in the folder and if you have many file or subfolder with your file, the process it's very long and memory up !
I make this, because certain system for make silent instal are need more files !
