Solution 1Recommended

Install Pending Windows Updates and Restart

Error 1935 and HRESULT 0x80070BC9 often indicate that the installation is blocked by pending system reboots or missing Windows components.

Software installations that rely on system assemblies can fail if Windows has updates pending a restart. Clearing these pending tasks is the most effective first step.

1
Open Windows Update

Press the Windows key, type "Windows Update" into the search bar, and select "Check for updates" from the search results.

2
Install Pending Updates

Click the "Check for updates" button. If any updates are available, click "Download and install" to apply them to your system.

3
Restart Your Computer

Once the updates are fully installed, click the "Restart now" button to reboot your system and finalize any pending assembly installations.

4
Run the Installer Again

Locate your Creative Suite 6 setup file, right-click it, and select "Run as administrator" to retry the Acrobat X installation.

Install Pending Windows Updates and Restart
Reboot Requirement: Sometimes Windows requires multiple restarts to configure updates completely. Ensure no updates are left pending before retrying the installation.
