I've tried with web43 and web53 NT examples and got the message:
Update of web folder required - Try pressing ctrl+f5 -Server is on version 10.45 but web folder is on version 10.46. However, 10.45 is the latest available version for download.
After Pressing ctrl + f5 still shows the message.
Turning "auto-check cached files" on and off doesn't fix it. (web server > extensions > thisWebServer > settings > perfomance).
I've deleted the c:\Clarion11\accessory\libsrc\win\NetWeb\ ,installed and compiled, without success.
C11.0.13505 - NT 10.45
