Hello everybody!
In today’s video, I’m going to tell you
about the problem “This app can’t run
on your PC”, why it appears, and how to
fix it, and about SmartScreen function which
can be one of the causes why you see such
a message, why Windows has such function and
how it can be configured or disabled.
Causes and solutions
If you see such a message, it means there
is a compatibility error.
The application you are trying to install
is incompatible with your operating system,
Windows 10.
For example, if you try installing an older
version of the program developed for an earlier
version of Windows, say, Windows XP.
In this case, you can try running this application
in the compatibility mode.
To do it, right-click on it, select Properties
/ Compatibility and then choose either “Run
compatibility troubleshooter” which will
search for problems and suggest you to “Try
recommended settings” Or, if you know for
which versions of the operating system it
is intended, check the box next to “Run
this program in compatibility mode for”
and select the appropriate version of the
operating system.
Then click “Apply” and try starting the
program.
Otherwise, you can go to the official website
of such program and try to find a newer version
compatible with your operating system.
If it doesn’t help, return to Compatibility
tab and check the box next to “Run this
program as an administrator.”
That’s because you may have this problem
if you don’t sign in as administrator.
Check this opportunity, and if it really happened
that way, switch to the administrator account
and try installing the program again.
You can run a program as an administrator
by right-clicking on it and selecting “Run
as administrator.”
If the problem can’t be solved that way,
check the bitness of your operating system.
If you’re using the 32-bit Windows and try
to run a 64-bit version of the program, the
error should have been expected.
Similarly, if you’re trying to install a
32-bit program onto a 64-bit Windows 10, this
error may also take place.
You can check this aspect by opening the computer’s
properties: go to File Explorer, right-click
on This PC and select Properties.
You can find this information in the line
“System Type.”
If the problem comes from bitness, there’s
only one solution - you’ve got to find the
proper version of the necessary application
and install it.
Other causes of the problem may be incompletely
downloaded program or viruses; try downloading
the application again or do it from a different
source.
There is a special video in our channel about
removing viruses.
And if you see a notice saying “This operation
has been cancelled due to restrictions in
effect on this computer.
Please contact your system administrator,”
this application is most likely disabled.

Windows 10 SmartScreen and how to disable
it
Sometimes, the error notice “This app can’t
run on your PC” can be false.
That’s why if the advice I have given you
this video didn’t help you and you still
face this error, and you still need to run
this app despite the warning, try disabling
SmartScreen filter.
To do it, click on the Start menu, go to Settings
/ Update & Security / Windows Defender / Open
Windows Defender Security Center / App & browser
control.
Here, disable “Check apps & files,” “SmartScreen
for Microsoft Edge” and “SmartScreen for
Microsoft Store apps” by checking the “off”
option.
After that, files and apps will not be checked
anymore.
Disabling SmartScreen with Registry Editor
You can try disabling the filter with Registry
Editor and with Local Group Policy Editor.
To open the registry, press the key shortcut
Win+R and type “regedit.”
Before doing anything to the registry, remember
that your actions can have irreversible consequences.
Windows may begin working with errors, some
apps or programs may not be able to start,
the operating system can crash or have problems
when booting.
Before you start modifying the registry, I
recommend creating a backup, just in case.
You can watch one of our videos to see how
to do it properly.
Find the link in the description.
You’ll have to create a file in the registry
- to do it, follow the path:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System
Right-click and select from the menu “New
/ DWORD (32-bit) Value.”
Name it “EnableSmartScreen.”
Open it and set the value as “0” then
click OK.
Now, close the Registry Editor and restart
the system.
After that, SmartScreen will be disabled.
To enable it, just delete this file from the
registry by right-clicking on it and selecting
the Delete option.
If editing the registry is a difficult task
for you, you can create a registry key.
I’ve already shown you how to create such
a file in the video on Task Manager; find
the link in the description as usual.
To disable SmartScreen, type the following
code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System]
"EnableSmartScreen"=dword:00000000
To enable SmartScreen again, the code is different:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System]
"EnableSmartScreen"=-
The first code creates an EnableSmartScreen
registry file, while the second code removes
the file.
Disabling SmartScreen with Local Group Policy
Editor
Unfortunately, you can’t use Local Group
Policy Editor in Windows 10 Home Edition,
but in other versions press Win+R and type
“gpedit.msc.”
The Local Group Policy Editor window will
open.
Then go to Computer Configuration / Administrative
Templates / Windows Components / Windows Defender
SmartScreen.
There are two sections, Explorer and Microsoft
Edge.
Each of them contains a policy setting “Configure
Windows SmartScreen” that allows you to
enable or disable the filter.
Open it.
Set the value to “Disabled” and click
Apply, then OK to save the changes.
Repeat the same steps for Microsoft Edge.
After saving the changes, close Local Group
Policy Editor, and the SmartScreen filter
will be disabled.
After you install the necessary application,
don’t forget to turn it on: with the disabled
filter, your system is vulnerable to threats,
and when the filter is on, you’ll improve
its security.
Disabling SmartScreen in Microsoft Edge
SmartScreen can also be disabled in Microsoft
Edge.
For that matter, go to the menu - Settings
- View advanced settings - scroll down until
you see “Help protect me from malicious
sites and downloads with SmartScreen Filter”
and disable it.
If you see errors again, the problem must
be in the application itself, not in the Filter.
DOSBox
If you need to run an old DOS program or game,
use the DOSBox emulator.
There is a special video guide about it in
our channel, and I will give the link in the
description.
