Build 081205 will not install on my G1. about android-vnc-viewer HOT 8 CLOSED

Check if you have enabled Settings->Applications->Unknown sources

Alas, that option is, indeed, enabled and has been since the first day I had the
phone.  The original version of this application installed and worked properly 
(up to
its limits, of course) and no settings have been changed since.  When I 
installed
build 081205, it uninstalled the original build and, now, the Application 
Manager
reports that no version of the VNC viewer is installed.  I rebooted the phone 
and
still cannot successfully install build 081205.

If you did not uninstall the old version before trying to install 081205, I 
found the
only way to get it to install is to factory default your phone and reinstall it
(unless you have root to remove all traces of previous version.  I'm a poor 
RC30 soul
myself)

This version is so significantly different that it was not "upgrade compatible"
so-to-say, but on a fresh data partition I was able to get it to install via ADB
Install and from the Browser as well.

Dear Sheetis,

When I installed 081205, I was informed that it would replace the old version 
so, of
course, I took it at face value.  Can you think of any way that I could figure 
out
what needs to be cleared, assuming I can find a new root hack or something?  For
obvious reasons, I hesitate to reset my phone.  There must be some way to do 
this! 
Thanks in advance...

I reinstalled the previous version. Uninstalled it properly via the Manage 
Applications menu and then installed this new build.

Install Successful.

Dear Flashworld,

Thanks so much!  It worked like a charm.

Regards,
Jeff
