Not so hard to figure out:

invoke SetRegKeysz , ADDR RegistryText, ADDR szKeyName,
ADDR szStringValue, SIZEOF szStringValue

Look what you are passing as the size of the string: "SIZEOF
szStringValue". That happens to be 12 bytes. I suspect you really wanted
"SIZEOF RegistryText" here.

Many registry strings are of type REG_MULTI_SZ, which consists of multiple
zero-terminated strings, where the end is denoted by two 0 characters.
Thus, passing the string length into a registry routine is generally good
practice.

However, it is easy to find a string's length with the "repne scasb"
instruction.
