Every program you install on a Windows PC usually starts from an EXE file. However, some applications are dedicated to modifying other types, and file formats are abundant, even for a single type of file. The one in question here is JAR, which can easily get associated with another type of program, making its sole purpose close to obsolete. Luckily, Jarfix comes to save the day.
Can be used on the go
For starters, JAR files are nothing more than special executable files created by Java Runtime Environment, which bundle up a variety of classes and functions to make the dedicated program work. However, some archiving utilities assume that you use JAR files to pack stuff inside, and want to read them by default. The lack of attention in a second can lead to JAR files not functioning as intended.
As mentioned above, you can rely on Jarfix to solve this issue. A neat advantage you notice right from the start is that you don’t have to go through any kind of trouble with an installer, because this application can be run right after it’s downloaded. As such, you can also carry it around on an USB Flash drive to fix similar errors on other computers as well.
Only needs to run once
The task is finished instantly and you don’t even need to restart your computer for JAR files to revert to their default form. A small prompt appears to inform you that the operation is successful, also pointing out the location of the Java Runtime Environment program on your computer, to check if it’s the correct one.
As suggested in the prompt, things might not work as intended the first time, but this only depends on the application that’s taking control of the JAR file. In case the problem persists, you can run Jarfix again with administrator privileges, although they’re asked for by default.
Other solutions also exist, but are not quite recommended for inexperienced individuals. A simple alternative is to completely remove Java Runtime Environment and install it again. If this doesn’t work, try to identify the source of the problem. Last but not least, registries can be tweaked, but this is best applied if you know what you’re doing, or you risk making matters even worse.
On an ending note
All in all, Jarfix is a nifty little repair tool that gets the job done quickly and flawlessly in most cases. It performed well under several situations and we managed to restore functionality for malfunctioning JAR files. It’s portable, doesn’t require any kind of accommodation, and can save a considerable amount of time if you really need to use a JAR program.
