your machine does not have isscript.msi engine .How can i fix it? I am now using Windows 7 Home premium edition.Please help me…

If you are encountering an error message that says “your machine does not have isscript.msi engine” while trying to install a program on your Windows 7 Home Premium edition, it means that the installation package requires the InstallScript engine to run. This engine is responsible for executing the installation script and installing the program on your computer.

To fix this issue, you can try the following solutions:

1. Download and install the InstallScript engine: You can download the InstallScript engine from the official website of Flexera, the company that develops it. Once downloaded, run the installer and follow the on-screen instructions to install it on your computer.

2. Check if the engine is already installed: Sometimes, the InstallScript engine may already be installed on your computer, but it may be corrupted or outdated. To check if the engine is installed, go to the Control Panel and click on “Programs and Features”. Look for “InstallShield” or “Flexera InstallShield” in the list of installed programs. If it is present, try repairing or updating it.

3. Run the installation package as an administrator: Right-click on the installation package and select “Run as administrator”. This will give the installation package the necessary permissions to install the program and its dependencies.

4. Disable User Account Control (UAC): UAC is a security feature in Windows that can sometimes interfere with the installation process. To disable it, go to the Control Panel and click on “User Accounts”. Click on “Change User Account Control settings” and move the slider to “Never notify”. Restart your computer and try installing the program again.

In conclusion, the error message “your machine does not have isscript.msi engine” can be fixed by downloading and installing the InstallScript engine, checking if it is already installed and repairing or updating it, running the installation package as an administrator, or disabling User Account Control. Try these solutions one by one until the issue is resolved.


In conclusion, I hope that the solutions provided were helpful in resolving the “your machine does not have isscript.msi engine” error message.
