Hi,
Error code 0xc00000007d is caused somehow by a misconfigured system file(s) in your operating system and/or by an uninstalled or incorrectly installed dll file.
There is a Windows command that allows you to check certain system files.
Open a "as administrator" command window (The word Administrator must appear in the title bar) and in this window type :
sfc /verifyonly
at the end of the verification operation, which may take "some time", any errors will be displayed or, if no errors: "The Windows resource protection program found no integrity violations."
If there are any errors displayed, to try to correct them, type:
sfc /scannow
Moreover, BEFORE installing Wampserver did you respect all the prerequisites?
> after the browser and notepad default setup it show that "stop service wampapache64" ...
This is the
normal sequence during installation and is not exactly what you just reported, but :
"Stop service wampapache64"
"Suppress service wampapache64"
"Stop service wampmysqld64"
"Suppress service wampmysqld64"
"Stop service wampmariadb64"
"Suppress service wampmariadb64"
"Installing mysql8.0.18/data directory (About 30 seconds)"
"Installing mariadb10.4.10/data directory (About 10 seconds)"
"Install service wampapache64"
"Install service wampmysqld64"
"Install service wampmariadb64"
Some operations are very fast, so we don't have time to see the message.
