I did a windows update and I can’t down load 1.5.3 or use 1.5.1 Just keeps saying NSIS_Error any help would be great.
If you google NSIS error you will get information about what it is and, possibly, how to get around it.
Thank you Paullarson
I tried that and I get more windows apps that want money (funny that)
Cheers
I tried googling NSIS before I suggested it to see if I got meaningful results and I did. Sorry you didn’t. I got the following info from Copilot. Maybe helpful. I’d try installing from the console window it suggests.
Fixing NSIS Error on Windows
The NSIS (Nullsoft Scriptable Install System) error occurs when an installer fails its integrity check, indicating that the installation files might be corrupted or incomplete. This error can prevent you from installing software on your Windows system.
Example
Error launching installer
Installer integrity check has failed. Common causes include incomplete download and damaged media
Common Causes and Solutions
1. Install the Program from Command Prompt
Running the installer through Command Prompt can bypass the corruption test and directly install the program.
cmd /c “path\to\installer.exe /NCRC”
2. Rename or Relocate the Installation File
Sometimes, folder issues or special characters in the filename can cause the NSIS error. Rename the file to a simple name without special characters or move it to a different directory.
# Rename example
installer.exe → setup.exe
# Move example
C:\Downloads\installer.exe → D:\installer.exe
3. Redownload the Program
If the installation file is corrupted or incomplete, redownload it from a reliable source.
4. Remove Virus and Malware
Viruses or malware can interfere with installers. Use antivirus software to scan and remove any threats**1**.
5. Update Your Windows
Ensure your Windows is up-to-date to avoid compatibility issues with the installer**2**.
6. Turn Off Your Windows Firewall
Windows Firewall might block the installer. Temporarily disable it and try running the installer again**3**.
# Disable Firewall example
Control Panel → System and Security → Windows Defender Firewall → Turn off Windows Defender Firewall
By following these steps, you can resolve the NSIS error and successfully install your software.
