Error: WriteFile failed => 0x5(5) when Makecert is run


Makecert -sv MyCert.pvk -n”CN=MyCompanyCert” MyCert.cer -b01/01/2009 -e 12/31/2018

While executing the above command, sometimes we get the following error.

Error: WrtieFile failed => 0x5<5>


The solution for this is to run the command prompt in admin mode.

This can be done by right-clicking on the cmd and selecting ‘Run as Administrator‘.

Hope this helps!
