How to open ISU file?
The main problem with InstallShield Uninstall Script Format is that the ISU file is incorrectly associated with programs. This is manifested by the fact that ISU files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the ISU file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install InstallShield
The first step is to check if the computer has the InstallShield program installed. This can be achieved by typing InstallShield into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support ISU files.
Programs to open ISU file
Remember to download programs supporting ISU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of InstallShield with ISU files
If, despite the installed application, the ISU file does not start in the InstallShield application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the ISU file with the InstallShield program.
Step 3. Update InstallShield to the latest version
If, despite the association of the InstallShield program with the InstallShield Uninstall Script Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Flexera Software, Inc. page and install.
Step 4. Check for the following problems with the ISU file
If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:
The ISU file may be unusually small compared to the original file. This is most often caused by a problem while downloading the ISU file. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the ISU file that we want to open. Sometimes virus-infected ISU files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the ISU files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular ISU file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Flexera Software
The program can also signal the fact of encryption. The encrypted file ISU except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move ISU to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the ISU file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
