Problem installing the Windows desktop app for Ricoh Theta S

Hi, I’ve got a couple of Ricoh Theta S’s and have been happy snapping away taking 360 pictures and videos using the Android mobile app.

It seems there are firmware updates available for the cam. I have firmware 1.11.

However, the Theta S Windows desktop app which you can download from doesn’t seem to install anything?

The download is called ‘SphericalViewer.exe’, it pops up with an install bar and then silently disappears. I tried ‘Run as Administrator’ and the same thing occurs. I can’t see anything being installed in Program Files or in the Windows Programs menu. This is on two different machines, one Windows 7 Pro and the other Windows 10 machines, both 64bit.

What am I doing wrong?


PS. the Windows live streaming application (UVCBlender_setup64.exe) installs and detects the Theta fine.

Hi alfski
Be sure you have the latest Adobe Air Version 23.0
normally it installs together with the RICOH THETA app
You might have Adobe blocked in your firewall

Awesome Svendus, yes needed Adobe Air. I feel like an idiot now!

I’m sure that information is in the install manual somewhere.
Ricoh should make it more obvious on the app download site!


Ricoh developers were on drugs when developing this, i can’t belive they don’t put it on their website, ot at least a frikkin warning from the installer!!

I agree it’s difficult to find. if you want the support notice for Adobe Air 24, here’s the link.

Was this problem with Adobe Air 24 ever resolved?

Hi iThink After the removal off Adobe Flash
Adobe Air are discontinued

check also this link
What to do next

Same here, I’m running RICOH THETA desktop app 3.15 on Windows 10. No problems.

One difference could be the version of Windows 10.

svendus is using Version 1909 (OS-version 18363.1316)

I’m using 20H2, 19042.685, which is considerably newer.

What version of Windows 10 are you using?

I’ve running 10.0.19042 Build 19042

I reinstalled just now. No issues.

It could either be a problem related to the older version or a country-specific language issue that we can’t replicate with our US-versions of Windows 10.
