Hi, I can put only 1 image per post so i’ll put links instead. GenICamBrowser application is loading infinitely on “Discover devices” when I start it : ![](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/53a451503413449448c37fb61013e4a63e9b9f17.png) ![](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/a7fbe7726ffe1423e60cf3cb602235ccc6688a53.png) There is nothing in the list and the cursor is loading. And all the icons are grayed out ![](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/4e260eef5e8f1397ad2c64e2843888824c7cd550.png) The only way that I have to have access to 3 of those few options is to go to View -\> Show / hide TLs… and click “OK” ![](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/9c0a858832bc8feb2c0fe98940f4b65d66af124b.png) Then : ![image](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/6e8768a1499e7ab4288042a8e9de66c1aa4c39f5.png) And if i click on that second icon to ignore the subnet, it does nothing more than “Ready”… ![](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/b36b6183c22a6a17318ef73bd6db1e820119b7d5.png) The mouse cursor is **always** loading.

Can somebody help please ? ---

I did not mention that the CPP program is working fine (except that it takes 1 photo instead of 10) : ![image](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/e4f0d7de740c5a09179683fff1f3763f7af586ac.png) ---

As said here [Cannot start GenICamBrowser - libpng missing](https://forum.commonvisionblox.com/t/cannot-start-genicambrowser-libpng-missing/523/17?u=ss_silkke), I needed to add a few env vars to the .xsessionrc file : ```auto CVB=/opt/cvb GENICAM_GENTL64_PATH=/opt/cvb/drivers/genicam CVGENICAM_REGISTRY=/var/opt/cvb/Registry GENICAM_CACHE_V3_0=/var/opt/cvb/genicam CVBDATA=/var/opt/cvb CVBCONFIG=/etc/opt/cvb ``` ---

In order to avoid “regenerating” Genicam.ini: Replace the content with … ```auto [SYSTEM] CreateAutoIni=0 ``` If the file is deleted a new file with … ```auto [SYSTEM] CreateAutoIni=1 ``` will be created. And then any access to the .vin driver will start a discover over all interfaces (that means all transportlayers). Which then results in your devices being inserted in Genicam.ini. ---

You may also run into an issue with services which are not running (because they are not called by debian). siGevSvc ( needed for “ownership” to a Gige Camera, otherwise you will not be able to open them) siLogSvc ( logging ) cvmgmtd ( our “management service” ) Should look like this: ```auto user@chartmannX64:~$ ps -ef | grep cvb root 798 1 0 09:39 ? 00:00:00 /opt/cvb-13.01.000/bin/siLogSvc -s root 900 1 0 09:39 ? 00:00:00 /opt/cvb-13.01.000/bin/siGevSvc -s root 1045 1 12 09:39 ? 00:00:03 /opt/cvb-13.01.000/bin/cvmgmtd user 3037 3027 0 09:40 pts/0 00:00:00 grep --color=auto cvb ``` I’m confident that they are running for you ( you are able to access a cam ). ---
