NSIS Error - what is it? How to fix?

Apparently, if not for everyone, then a lot of fans of modern computer games had to deal with the situation when, at the start of the installation distribution, an incomprehensible error NSIS Error appeared. What is it, we'll try to figure it out.

What is NSIS?

Before considering the failure itself, leading to an error of this type, it is necessary to understand what the system itself is.

In general, NSIS is a special script system based on the original application installation technology from Nullsoft, which is one of the most famous developers of modern computer games. In addition, as noted by many experts, the NSIS installation system acts in its own way as an alternative to the standard Windows installer, called InstallShield.

The technology itself is much simpler than the one used in Windows operating systems, and works if not faster, then much more correctly. However, it is not immune from the appearance of failures with errors like NSIS.sf.net/NSIS Error or something else. Consider the nature of the error itself.

NSIS Error: what is it?

In simple language, the error indicates the impossibility of either triggering or completing the installation of the game or another application by the system itself. Here's the message NSIS Error. What is it, from the point of view of the system itself? But only that the standard installer for some reason alone or forcibly blocks its work.

The fact is that the execution of any script (especially installation) causes a lot of consequences. These include, for example, changing the system configuration of the computer. It goes without saying that Windows with enhanced security settings can recognize the installer as a potentially unwanted program. Although, in general, this is not the only reason for this kind of failure.

What is NSIS Error in terms of operating system?

It was just the only example related to Windows directly. However, let's expand on the problem of the error simulations of NSIS Error. What it is? It can be noted only that the installation system itself is recognized so correctly in the installation that neither the performance, nor the performance, nor the speed of Windows is affected in any cardinal way.

In the case of direct conflict with the system, which is very rare, here primarily the role of setting up a protection system for "operating systems", in particular, a firewall (firewall). How to resolve this situation, will be discussed a little later.

Variants of error messages

The error itself may contain several basic modifications. In addition to the main options mentioned above, there may be disruptions in the operating systems themselves, such as NSIS Error-ZM (Windows 7, as the platform should be used by default, not XP, in which the gamer tries to install the game).

One can distinguish one more type of failure. This error is NSIS.sf.net/NSIS Error. It indicates that the Source Forge source, from which the SF contraction occurred while trying to access the Network, could not independently verify the integrity of the installation distribution, since the configuration with respect to the initial distribution was changed (possibly due to viruses).

The same applies to the variant of the NSIS.sf / NSIS Error error. Only in this case, self-test is triggered, and not the reference to the source in terms of data comparison. Now a few words about how and what situations can be corrected by the most simple methods.

The main causes of the failure and the simplest methods of correction

So, one of the most basic reasons for the occurrence of errors of this type is called damage to the installation distribution.

As is already clear, one of the options may be to change the installation files (and not always just the main "exeview"). What to do in this case? Simply check the system with any powerful antivirus software. Naturally, it is better to use non-installed programs in the system, and portable versions like Dr. Web Cure It. It is believed that it is this small package that can detect viruses in Nullsoft installers.

On the other hand, the damage to the installer or the archive in which it is located (which occurs most often) may also be related to the so-called "underfunding" if it was downloaded from the Internet. You can sometimes unpack the archive, but the files necessary for the full correct installation of the game, it may not be enough.

In this case, it's best to download the distribution kit again. If this does not help, then it's better to turn to some other Internet resource. It may very well be that the site itself initially contains an incomplete distribution kit.

Equally common are situations where there is not enough free space on the disk or in the logical partition. As an exit - removing unnecessary files, unused programs, etc., or selecting another partition for installation.

Another reason for installing from an optical media (CD / DVD-ROM) can be mechanical damage to the media (scratches, chips, potholes). In this case, it's better to rewrite the distribution to another disk, or, even better, to a flash drive. But in some cases, the installer can also not accept the flash drive. Especially often this occurs when the game is recorded on several disks, and during the installation it is required to insert the next medium (necessarily in the drive) to continue or end the process.

As already mentioned, the error may appear due to a conflict with the security system. Here you just have to disable for a while either the antivirus, or the firewall, or both together (which is even better). If you frequently install games from Nullsoft so that you do not disconnect protection components each time, you can simply add this process to the exception lists, especially since Nullsoft installation files always have a trusted publisher certificate.

Finally, the conflict can be caused by some other applications running in the background. In this situation, you can try to simply reboot the computer system and try to reinstall the installation.

Conclusion

In general, the very nature of the error refers only to damage to the distribution or the media from which the installation is made. To the operating system itself, this has to do with, as they say, so far. Actually, the method of correcting the problem is such that the user can cope with it even with the initial level of preparation.
