Another installer is running

[nancya80642821]

When trying to install Adobe Lightroom 6 on my new computer, with Windows 10, I am getting the following message. "Another installer is currently running, which must be closed before installing this product.  Please close other installers."  I do not have anything else running.  I have shut down my system and upon starting up again, immediately try the install.  I get the same message.  Any suggestions?

Hi,

I suggest you to Stop the Windows Installer service by following the steps below:

Press Windows key + R, type services.msc and press Enter.

Double click on Windows Installer and in General tab, click on Stop.

Click on Apply and OK.

After the steps are complete, restart the system and Start the Windows Installer service by following the steps below:

Press Windows key + R, type services.msc and press Enter.

Double click on Windows Installer and in General tab, click on Start.

Click on Apply and OK.

Let us know if that  helps!

Regards,

Tanusree

I had to start and stop it several times and restart twice but doing this a couple times ended up working for me. Thanks!

It won't work for me--same issue, the Stop button is unavailable.

[brices71555620]

the stop button is grey, and unavailable.

If the stop button is grayed out.  Hit alt, ctrl, delete.  Go to services, find windows installer, hit the stop service button, and shut down.  When aging install it will walk you through cleaning up the old (bad) install and start the new install.

Thank you, this did work and I was able to install the product.

Hi, This did not work for me because I can't click on the "stop" button. It's disabled.

What do I do now?!?!?!!?!

Can you please explain how one does this for Macs?

If the stop button is grayed out , try this method too , go to Control Panel - view by Small icons- Administrative tools -Services- Windows Installer - Right click - Stop.

Hi

Tried the three methods but didn't work

1) Windows key + R, type services.msc and press Enter. Double click on Windows Installer and in General tab, click on Stop. Click on Apply and OK.  >>> Stop is grey

2) alt, ctrl, delete.  Go to services, find windows installer, hit the stop service button, and shut down >>> This operation could not complete, The requested control is not valid for this service

3) Control Panel - view by Small icons- Administrative tools -Services- Windows Installer - Right click - Stop >>> Stop is grey

What can I do? 

Try installing Premier Elements 2020

Thanks

I continue to have this issue. Brand new Windows 11 PC despite trying the fixes below. I have all options greyed out.

restart your computer and retry whatever you're doing.

if that fails, reset the cc desktop app:

make sure it's in the foreground, then press:
Win: Ctrl + Alt + R
Mac: Cmd + Opt + R




if that fails, repair per
https://helpx.adobe.com/download-install/kb/creative-cloud-install-stuck.html



if that fails, uninstall using the correct uninstaller from
https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-mes...
and then reinstall*



if that fails, do a clean cc install carefully following each applicable step:

uninstall every cc app including preferences per https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html

then uninstall the cc desktop app, again using the correct uninstaller per https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-mes...

clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html

check for, and if available, update your os

repair all ms visual c++ versions that can be repaired

update your ms visual c++, if it can be updated

restart your computer (don't skip this)

reinstall the cc desktop app*



*use the "alternative download links" at the bottom of the page at https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html

use the desktop app to install your cc programs/trials

Hi all, I know this is an old post, but since this is a recent error many people are stumbling upon as "Error 87", I'd like to share this tutorial, as any solution I found in these pages didn't work for me: 
I found this video here that allows you to "reset" only your operating system, without touching your files and without having to fully wipe your machine. This fixed my "Another Installer is Already Running" error 87. Do back up your file just to be on the safe side!

Good luck!

@Leonardo3861041023ox 

thanks for that.  that was useful and something i didn't know you could do.

[Leonardo3861041023ox]

No problem, one thing I forgot to mention here, if people are trying to fix the Error 87, after you are done resetting your OS, if you get error 87 again. restart your pc one more time, and then run the Adobe installer/updates (or at least this is what happened to me, weirdly!).

thanks again.
