Solution 1Recommended

Manually Install the WCChromeExtn.crx Extension File

Locate the local extension file from your Adobe program folders and manually install it by dragging it into Chrome's extension manager.

Chrome's security updates often prevent third-party applications from silently installing extensions in the background. Manually forcing the installation using the official local file bypasses this restriction.

1
Open Chrome Extensions

Launch Google Chrome, click the three-dot menu in the top right corner, navigate to 'Extensions', and select 'Manage Extensions'. Alternatively, type 'chrome://extensions/' directly into your address bar.

2
Enable Developer Mode

In the top right corner of the Extensions page, toggle the switch for 'Developer mode' to the 'On' position to allow manual installations.

3
Locate the CRX File

Open File Explorer and navigate to 'C:\Program Files (x86)\Mozilla Firefox\plugins\WCChromeExtn'. Look for the file named 'WCChromeExtn.crx'. If it is not there, check the temporary files extracted during the Acrobat installation for 'Data1.cab' and extract the .crx file.

4
Drag and Drop to Install

Click and drag the 'WCChromeExtn.crx' file from the File Explorer window directly into the Chrome Extensions page.

5
Confirm Installation

A prompt will appear in Chrome asking for confirmation. Click 'Add extension' to complete the installation.

Manually Install the WCChromeExtn.crx Extension File
Avoid Unofficial Sources: Always use the .crx file provided by your official Adobe installation directories. Downloading extension files from unofficial third-party sharing sites poses a severe security risk.
