The error for which the description refers to an unknown software exception is mainly encountered by Windows users of the seventh modification and version of XP, and the failure itself usually appears at the stage of installing certain programs or when starting already installed applications after some time has passed. Unfortunately, the operating system does not give any detailed transcripts of this problem, but simply offers to close the problematic applet, which most users are puzzled to say the least. How to deal with such situations, find out further.
What is the error with the exception unknown software exception (0xc000001d) and the reasons for its occurrence in Windows
By its nature, a failure is not particularly critical and does not affect the performance of the operating system itself. But with user programs, serious problems can begin. In most cases, the appearance of a failure with the exception of unknown software exception is associated with the fact that outdated equipment does not support the installation of software updates or new applications that are not designed for the existing hardware configuration.
First of all, this concerns the processor, which cannot process new instructions and directives, because it simply "does not know" them. It is noted that the described problems most often occur with multimedia programs, games or applications like Skype, which actively use all kinds of additional platforms and components (.NET Framework, Adobe Flash, etc.).
But the main reasons for the failure with an unknown exception unknown software exception are usually called the following:
- mismatch of new versions of computer configuration software;
- failed or incorrectly installed updates of the OS itself;
- outdated drivers;
- lack of additional platforms or their updates;
- exposure to viral applets.
Based on a sample list of root causes, we will seek the best solution to fix the problem for each specific case. But it’s worth noting right away that it is usually impossible to find out the root cause on the fly, so you may need to complete the entire range of proposed measures. Errors of this nature can occur not only in the above versions of Windows, but also the methods for fixing them proposed below can be used in any of the known operating systems of the entire family.
Fix crash when application installation fails
When you try to install programs, the reason looks quite simple and even banal. If you are going to install a more recent version of an existing application or install a new modification from scratch, the essence of the failure with the exception unknown software exception 0x000001d is reduced to a compatibility problem. In this situation, you can try to install the software version as an earlier version.
It also does not hurt to run the installer file itself in compatibility mode, choosing a lower rank OS (if any) in the list.
Note: for the installed program in Windows of the latest modifications, you can immediately set the launch in compatibility mode through the properties of the shortcut of the executable file.
If any program was updated independently, but with your consent (for example, the same Skype), do not rush to delete it.
To get started, try installing updates for the .NET Framework and the Adobe Flash Player extension. In the case of games, it does not hurt to check for DirectX updates. If this does not help, and an error with an unknown software exception will be thrown again and again, uninstall the problematic application and install an earlier modification instead. Somewhat inconvenient, but nothing can be done. Then, in the settings, if possible, completely disable the automatic search and installation of updates for the application itself.
System rollback and system update actions
If the fault of the described failure is caused by updates of Windows itself, which was especially often noticed by the "seven", and since then it has started to sin the "ten", delete the last installed packages using the programs and components section where you need to click on the viewing link installed updates.
The best option is to use a special uninstall software like iObit Uninstaller, which automatically cleans up the residuals after removing the main components.
If this does not work, try to roll back the system using the standard method, choosing the restore point, which in time precedes the time the errors occurred.
Driver Status
Conflicts at the hardware level are often associated with obsolete drivers. In this case, it is strongly recommended that they be updated, and the main emphasis be placed on equipment that is involved in the problem program (video cards, sound cards, etc.).
Finding and installing updates through the “Device Manager” is an absolutely thankless task. Anyway, Windows usually does not find anything worthwhile. It’s much easier to use automated applications and kits like Driver Booster or DriverPack Solution and update drivers for all devices. Search and installation will require an uninterrupted internet connection.
Note: if the error occurs precisely after updating the driver, in the “Device Manager” roll back.
A special case of the appearance and correction of errors
As an example of eliminating the described malfunction, we can cite the well-known game Apex Legends (the unknown software exception throws either the video card is not recognized, or indicates the setting of unsupported graphics parameters, or reports the presence of an outdated processor). To get started, as mentioned above, update the graphics driver.
If the effect is zero, you can fix the crash with the unknown software exception in Apex by setting the graphics options shown in the image below.
Note: in some cases it may be necessary to update the Visual C ++ component by downloading it from the official Microsoft website.
As for the processor, there are no options other than replacing it!
Using optimizers and virus checking
Finally, it will be useful to check the system for viruses, and also try to optimize the registry. In the first case, preference should be given to portable anti-virus scanners, in the second - to special optimizers like Advanced SystemCare, CCleaner and the like. It is possible that removing obsolete or incorrect keys that refer to missing objects will allow you to completely get rid of errors with various exceptions (and not only 0x000001d).
