I'm absolutely new to Portable Apps so please forgive for any unnecessary questions.
I'm trying to run Java JRE. When launching "JavaPortableLauncher.exe" I always get the following alert:
"jPortable Launcher (64-bit) cannot be started. You may wish to re-install to fix this issue. (ERROR: open could not be found)"
The same thing happens when I try to launch 32-Bit version of the "JavaPortableLauncher.exe".
Here are the steps I did to install the Java application. I downloaded and ran the file "jPortable64_8_Update_231_online.paf.exe". During the install attempt I got an alert claiming that the actual Java application was not available. So I did some research and found out that there seems to be a problem with downloading the respective Java file from the Java site during the install. The research recommended downloading the appropriate java file and including it in the same folder where the "jPortable64_8_Update_231_online.paf.exe" is located at on my drive. So I downloaded the file "jre-8u231-windows-x64.exe" from the Java website and put it in the same folder. This time the installation went without any alerts. The Java files where installed to my USB stick at "K:\PortableApps/CommonFiles/Java64"
After that I downloaded and installed the "JavaPortableLauncher64_5.0.paf.exe". It resides at "K:\PortableApps/JavaPortableLauncher64". When I run "JavaPortableLauncher.exe" from "K:\PortableApps/JavaPortableLauncher64" I get the error message mentioned above.
So I did the whole procedure for the 32-bit versions as well:
I paired "jPortable_8_Update_231_online.paf.exe" with "jre-8u231-windows-i586.exe" in the same folder and installed them to "K:\PortableApps/CommonFiles/Java". I downloaded and installed "JavaPortableLauncher_5.0.paf.exe" which ended up at "K:\PortableApps\JavaPortableLauncher". But same thing here. When I run "JavaPortableLauncher.exe" from "K:\PortableApps\JavaPortableLauncher" I get the error message.
Any ideas what goes wrong?
Any help is really appreciated. Thank you
