BiosConfigUtility - Password file does work for get but not for set

[KaiBO]

Hello,

i have a problem with automatically set the bios settings over the bios configuration utility.

I did the following steps:

1. Create password file

2. set password through biosconfigutility and password file (biosconfigutility64.exe /newsetuppassword:pass.bin)

3. get config (biosconfigutility64.exe /get:config.txt /cpwdfile:pass.bin) <- works like a charm

<BIOSCONFIG Version="" Computername="PC21084" Date="2021/09/17" Time="09:13:00" UTC="2">
        <SUCCESS msg="No errors occurred" />
        <Information msg="BCU return value" real="0" translated="0" />
</BIOSCONFIG>

4. change some settings in the config file

5. set config (biosconfigutility64.exe /set:config.txt /cpwdfile:pass.bin) <- does not work

<BIOSCONFIG Version="" Computername="PC21084" Date="2021/09/17" Time="09:14:09" UTC="2">
ERROR: Error during CryptAcquireContext. LastError = 0x8009000f
        <ERROR msg="Unable to decrypt password file: pass.bin" />
        <ERROR msg="BCU return value" real="10" translated="10" />
</BIOSCONFIG>

 I cannot figure out what my mistake is.
