Error after updating to new ccleaner version v5.26.5937 (17 Jan 2017)

After auto-updating my ccleaner pro version to new version v5.26.5937 (17 Jan 2017)

i get the following error message whenever i try to open "chrome://plugins"

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This site can’t be reached

The webpage at chrome://plugins/ might be temporarily down or it may have moved permanently to a new web address.

ERR_INVALID_URL

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

But with the _older_ ccleaner pro version v5.25.5902 (13 Dec 2016) i could read these 4 wanted "chrome://plugins" -

1. Plugin "Chrome PDF Viewer"

2. Plugin "Native Client"

3. Plugin "Shockwave Flash"

4. Plugin "Widevine Content Decryption Module"

What should i do now and how to do this:

Return to _older_ ccleaner pro version v5.25.5902 (13 Dec 2016) ??

Sincerly your chrome_lover,

always using google chrome developer since many years:

last update was

"Dev Channel Update for Desktop, Tuesday, January 17, 2017

The dev channel has beekn updated to 57.0.2984.0 for Windwos, Mac and Linux

G'day @chrome_lover,

always pick the lowest hanging fruit first - so try reinstalling those 4 plugins.
