Hello,

&nbsp;
  

New instance of&nbsp;PVRTextToolGUI is unable to open an already compressed PVR texture.
  

My scenario : 
  

1. I use the PVRTextToolGUI to Encode a Texture to PVRTC2 or PVRTC4 format.
  

2. I select the Output Tab and Save the Compressed file(Say a.pvr).
  

3. I Open a NEW instance of the PVRTextToolGUI.
  

4. I Open the already saved PVR File(a.pvr).
  

&nbsp;
  

5. I get an Error saying :
  

&nbsp;&nbsp;&nbsp; File Open Failed:
  

&nbsp;&nbsp;&nbsp; An error ocured in the pixel format decoder.
  

&nbsp;
  

Can somebody help me with this Please?
  

I require the PVRTextToolGUI to open .pvr file

I can’t reproduce this bug here - which OS are you using and exactly which SDK build version of PVRTexTool (it says under Help-\>About…)?  
  
  
  
  
  
Is it possible for you to send an example .pvr file that won’t open to [devtech@imgtec.com](mailto:devtech@imgtec.com)?
